c++ - ctags无法正确解析stdio.h

Question

我正在尝试将Ctags与VIM一起使用，而我都是两者的新手。为了测试ctags有用的程度，我决定通过一个非常简单的测试，即解析/usr/include中的 header ，以便我可以自动完成一些非常基本的功能。

当我运行命令

 ctags  --c++-kinds=+p --fields=+iaS -f ~/.tags/tags /usr/include/*.h

然后输出打印

很明显，ctags错过了一些非常明显的功能，例如fopen，但其中却包含了fclose等功能。使用ctags解析时，我是否缺少某些选项？

Answer 1

在您的ctags命令中添加一个-I__wur，您将得到想要的结果。__wur是__attribute__ ((__warn_unused_result__))的宏
